I'm trying to align an input 15 kHz signal with a 20% duty cycle with an output 15 kHz signal with a 50% duty cycle. To do this I'm hooking up the input signal to a direct capture interrupt and Timer 1 Channel 4 and using the HAL_TIM_IC_CaptureCallba...

I'm currently using the STM32 L476RG for an application where I need to communicate with peripherals through SPI at 1.8V. Currently I'm using the TXB0108 bidirectional logic level shifter to convert my SPI lines from 3.3V to 1.8V but there are proble...

I'm confused what you mean by "set up the timer for the PWM output but don't enable it in TIMx_CR1.CEN"? Also, how can I connect the input signal to a trigger without using the Compare Pulse?

These are my timer settings. I have TIM1 as an input capture on channel 1 with the trigger output set to Compare Pulse (OC1). I put TIM2 in trigger mode with the source as ITR0 and PWM on channel 1. I'm toggling a GPIO in the input capture interrupt ...

Using the slave mode path, what type of Trigger Output (TRGO) should be used for an input capture timer? The only options are output capture ones.

I'm already doing that in the main function. Am I supposed to call it more than once?

How can I make sure the timer IC is ready? The only line of code I have outside of the default and ISR is HAL_TIM_IC_Start_IT(&htim1, TIM_CHANNEL_4) which I call in the main function before the loop. Here are my timer 1 settings: The trigger slave mo...
